I used to prefer the 65 princeton cleans to the pro junior but after this upgrade i have not played my princeton at all.
Pro junior cabinet upgrade.
The resonance and sonic size of the amp is vastly improved.
These features truly earn the pro junior iv its pro title.
In this case i feel like a 10 would sound spectacular in a blues junior cab whereas the 12 speaker never quite does it for me in a blues junior.
This larger cabinet actually weighs less than the smaller stock cab due to pine and birch construction so even if adding a heavier speaker.
Fender ships the pro junior iv with groove tubes so you don t need to budget for a tube upgrade.
Features the pro junior iv features a 15 watt tube circuit driven by a pair of el 84 power tubes and two 12ax7 preamp tubes with a solid state rectifier.
The overall tone is ok but they can sound boxy and small and for this reason many guitar players write off the pro junior as a non gig worthy amp.
From the factory the pro jr should have came with either an 8 speaker like a high powered champ or came in the blues junior box and the the blues junior should have either came with a 10.
Upgrade your good little amp to great pro junior super champ xd x2 blues junior etc you may have noticed that over the last decade or so fender has released some cool little tube amp designs like the ever popular straight up tube amps the blues junior and the pro junior as well as the tube hybrid super champ xd and x2.
The fender pro junior is a great sounding little amp and our 1x12 pro senior cabinet upgrade is a mod that will really open up the tone and make your pro jr.
